Integrates with mxHERO's Mail2Cloud Advanced service to search across massive multi-account email repositories using vector database technology, providing secure links to original emails and filtering capabilities that exceed LLM context limitations.
Review before connecting
The server requires authorization, so only its authentication surface was graded. Review that posture — and the tools it exposes once authenticated — before connecting.
Scanned 8 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The mxHERO Mail2Cloud Advanced MCP server requires authorization, so its tools were not enumerated during the automated scan. Its published description reads: "Integrates with mxHERO's Mail2Cloud Advanced service to search across massive multi-account email repositories using vector database technology, providing secure links to original…". It communicates over Streamable HTTP, and requires authorization before its tools can be called. MCPGrade currently rates mxHERO Mail2Cloud Advanced N — the server requires authorization, so only its authentication surface was graded and the tool surface could not be assessed without a valid token. Its most notable findings include "Open dynamic client registration" and "PKCE S256 enforced". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check mxHERO Mail2Cloud Advanced's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.

Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
Unauthenticated DCR lets anyone register a client — an abuse and confused-deputy surface.
RecommendationPrefer CIMD; if DCR is offered, gate or rate-limit it.
The authorization server enforces PKCE with S256.
